Limit categories on "next" and "previous" portfolio navigation?

[designpoint]

I’d like the ability to limit the categories that the “next” and “previous” portfolio navigation returns results from. We have several different types of projects on a website we’re developing, and I’d really like for the navigation to only pull the portfolios from a particular category. Is that a possibility?

To clarify, if we have a portfolio category of “retail”, I’d like the links at the bottom of the site that link you to the next and previous portfolio items to only link to the other portfolio items in that category. Is this something you could help us with? Thanks.

Hi,

WordPress only has the ability to specify if the next/prev posts linked should be from the same category, please read here: http://codex.wordpress.org/Function_Reference/next_post_link

You can implement the above in single-portfolio.php, at lines 177 and 178.

OK, so I added TRUE to the lines on 177 and 178 but instead of limiting the categories, it eliminated the links entirely. Here’s one of the lines, so you can tell me if I did this correctly or if I screwed it up.

<div class="nav-previous"><?php next_post_link(__('<i class="icon-chevron-left"></i> <span class="nav-text">%link</span>', 'swiftframework'), '%title', TRUE); ?></div>

If you have no other posts in the category that post is from, it won’t show any next/prev links, as this limits navigation to posts within the same category.

Understood, however I’ve made sure that there were multiple posts. Was there anything wrong with the code I pasted?

The only other issue I could think of is that many of my portfolio items belong to multiple categories. Would that break it?

The code looks fine to me; Ed, is there something else that might prevent it from working correctly?

Cosmin –

The only thing I can think of is having the portfolio items in more than one category.

Hi there,

This is actually an issue with WordPress, which is fixed by this plugin and it’s functions – http://wordpress.org/plugins/previous-and-next-post-in-same-taxonomy/

Hope that helps.

Hi Ed, I have installed and activated the plugin, and no changes. This particular video is only in one category which has several items. Still can’t understand why the code isn’t working, Any thoughts?


<div class="pagination-wrap portfolio-pagination full-width clearfix">
<div class="nav-previous"><?php next_post_link(__('<i class="icon-chevron-left"></i> <span class="nav-text">%link</span>', 'swiftframework'), '%title', TRUE); ?></div>
<div class="nav-next"><?php previous_post_link(__('<span class="nav-text">%link</span><i class="icon-chevron-right"></i>', 'swiftframework'), '%title', TRUE); ?></div>
</div>

Try changing the functions to:

be_previous_post_link()
be_next_post_link()

As per the new plugin.
